Description
製造例1:MCM-22(P)ナノ板状単層ゼオライトの製造
製造例1-1:MCM-22(P)粒子の合成
面はそれぞれ、約7.2゜、26゜で現れる。)のXRDピークは残っているのに対し、(00l)面のXRDピークが消える様子が観察された。このような様子は、この物質に見られる典型的なXRD特徴であり、多くの文献で報告されている(図2(a))(Corma,A.et al.,Nature,1998,396,353-356;Corma,A.et al.,J.Catal.,2000,191,218-224;Frontera,P.et al.,Microporous Mesoporous Mater.,2007,106,107-114)。HT_S_HとRT_NSのXRDが類似に示されたが、(100)面と
面の強度がRT_NSにおいてより目立ち、これは、MWW型ゼオライト構造がよく維持されることを意味する。HT_S_HとRT_NSの形態に見られる差異は、XRDパターンに見られる構造の差異と類似していた。HT_S_Hの粒子は丸い縁を有し、より小さくて非定形化された粒子が観察された(図8(b)で暗黄色の矢印で表示)。RT_NSにおけるMWW型ゼオライト構造が維持されることは、温和な条件で層間膨脹過程が行われるためと見なされる。80℃で層間膨脹を行う場合、XRD強度の著しい減少と共にS/N比の減少を確認した(図9)。図9から、80℃での層間膨脹処理後の層間間隔が約1.4nmであることを確認したが、既存MWW構造は深刻な程度の構造崩壊が進行されることを確認した。一方、常温で層間膨脹処理して得た粒子は、層間間隔が同一であるが、MWW型ゼオライト構造が維持された(Maheshwari,S.et al.,J.Am.Chem.Soc.,2008,130,1507-1516;Schwanke,A.J.et al.,Microporous Mesoporous Mater.,2017,254,17-27)。また、MWW型ゼオライトの板状構造の保存は、特に8~10゜範囲のXRDパターンから解析できる。8~10゜範囲のXRDパターンは2D板状構造ゼオライトの積層程度を説明するのに多く使用された。HT_S_HのXRDパターンにおいて8~10゜付近に1つの広いピークが現れ(図2(a))、これは、MWWゼオライトの層がc-軸に対して非常に無秩序であるということを意味する(Roth,W.J.et al.,Microporous Mesoporous Mater.,2011,142,32-36)。しかし、RT_NSの場合、(101)面と(102)面をそれぞれ反映する8.0゜と9.8゜周囲の2つの別個のXRDピークが観察された。この様子はc-軸に沿って整列された構造を提案するが、これは単層が不規則に積層されているMCM-56との様子と一致する(Wang,L.L.et al.,Microporous Mesoporous Mater.,2008,113,435-444;Polozij,M.et al.,Dalton Trans.,2014,43,10443-10450;Juttu,G.G.et al.,Microporous Mesoporous Mater.,2000,40,9-23)。MCM-22(C)粒子のディスク状の形態と違い、RT_NS粒子はカール状(図8(c)で橙色の矢印で表示)を示すことが分かるが、これは、前にナノメートル厚のMCM-22板状構造でも観察された様子である(Varoon,K.et al.,Science,2011,334,72-75)。HT_S_H及びRT_NSを合成する時に用いる後処理工程は、非常に再現性が高く、この結晶構造は陽性子交換後にもよく維持される(図10)。
構造内シリカが除去される過程によって不回避な非晶質シリカが形成されたためである(Ogino,I.et al.,J.Am.Chem.Soc.,2011,133,3288-3291)。低いP/P0領域で吸着されたArの減少は、微細気孔の量が減少することを示す。一方、0.7~2.0nm範囲の知られていない微細気孔は増加した。また、HT_S_Hの吸着等温線に見られるP/P0 10-3以上での急激な増加と微細気孔の変化は、HT_S_Hが中間気孔サイズからなる多孔性シリカを代表するMCM-41及びSBA-15と類似する(図15)。MCM-41及びSBA-15の気孔サイズ分布(図15(c))に基づいてHT_S_Hが非晶質シリカによる微細気孔からなっていると結論付けることができる。N2吸着等温線を改善されたt-プロット(Galarneau,A.et al.,Langmuir,2014,30,13266-13274)を用いて推定した定量分析は、微細多孔性表面積及び体積がMCM-22(C)に比べて約22%及び11%に減少することを示す(表2)。Ar吸着等温線に基づくH-K方法は、ゼオライト気孔に当該する微細気孔が約0.9%まで減少することを示す(表2及び図13(b)、0.001cm3・g-1)。その代わりに、中間サイズの気孔及び外部表面は大きく増加して全表面積の大部分を占める。このような中間サイズ気孔及び外部表面積の増加は、上に言及したように、新しく形成された非晶質シリカに起因したものと見なされる(図3(a1))。HT_S_Hに対する詳細な結果及び以前結果との比較を、表3に示す。
